I was unable to deploy Sportsclub example on EAP 6.1.1 with Snowdrop 3.0.1.Final-redhat-1. To get Snowdrop I used link: https://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/WFK/view/WFK-PROD-CI/job/wfk-prod-distribution/314/
Sportsclub (sportsclub-invoicing-ejb and sportsclub-subscriptions-ejb modules) depends on snowdrop-deployers.jar, but this has been removed from Snowdrop distribution. Furthermore, the snowdrop-deployers-core.jar has been removed from wfk repository. I have tried to replace the snowdrop-deployers dependency by snowdrop-interceptors, but there is a problem. The snowdrop-interceptors.jar depends on spring-core.jar (so does snowdrop-deployers-core.jar), which causes the spring-core.jar to be present in the sportsclub.ear. When deploying such ear, the linkage errors occur because there is spring-core.jar installed as a module (this was done as a part of snowdrop installation process).
In previous version of Snowdrop there were snowdrop-deployers-core.jar (which is quite similar to current snowdrop-interceptors.jar), but there were also snowdrop-deployers.jar that depended on snowdrop-deployers-core.jar with provided scope and Sportsclub depended only on this snowdrop-deployers.jar, thus the spring-core.jar weren't packaged inside sportsclub.ear. There is no such equivalent for snowdrop-interceptors.jar.
